XVI INTRODUCTION. 



This ■work will not embrace the description of the Tertiary 

 Cephalopoda in the British Museum, as they are being catalogued 

 by Dr. A. H. Foord and Mr. G. C. Crick'; but it may be mentioned 

 that so far as Australasia is concerned only two Tertiary species, 

 viz., Aturia atari, Basterot, var. australis, M'Coy, and Nautilus 

 geelongensis, Poord, are found in the collection, and they have 

 already been dealt with.- 



Finally, I must express my indebtedness to several friends who 

 have assisted me, from time to time, during the preparation of this 

 Catalogue. Foremost stands Mr. Edgar A. Smith, whose courtesy 

 in permitting me frequently to consult the modern moUusca in the 

 Zoological Department of the Museum, and for much advice in 

 regard to matters of nomenclature, I most thankfully acknowledge ; 

 Mr. R. Bullen I^ewton has also rendered me assistance in regard to 

 nomenclature, for which I tender him my best thanks ; Mr. B. B. 

 Woodward has on several occasions given me the advantage of his 

 extensive knowledge of bibliography, which has been of signal 

 service, and for which I am greatly indebted to him ; Mr. C. D. 

 Sherborn has kindly permitted me to refer to the MS. of his 

 Index Animalium. Professor Tate, of the University of Adelaide, 

 kindly sent me a collection of specimens and copies of his publi- 

 cations on the Tertiary moUusca of Australia, which have been 

 of much use ; whilst I am indebted to my friend Mr. H. W. 

 Burrows for his ready assistance in reference to the classification 

 of mollusca. To Miss G. M. Woodward I must also tender my 

 thanks for the preparation of the beautiful drawings which adorn 

 this Catalogue,
